Hello all,

I broke the vacuum hose fitting of this sensor while reinstalling the fuel injection stuff. (replaced the fuel pressure dampener)

I've downloaded the manual; I'm not able to decipher which sensor it is.



Also, after running the car for about 30 minutes to check for fuel/vacuum leaks I let it sit for about an hour. When I went to restart it was flooded. I know the procedure to unflood it, done it a few times before. I'm just wondering why it would flood in general and why it is so unbelievably flooded now. I'm talking a fog blowing out the plug holes.

Any help/guidance is greatly appreciated here.

The gray one is the switching solenoid. It's job is limited, and it's for emissions purposes only. I know some people have had some luck superglueing the broken plastic piece back on those, or you can pick up a used replacement. Those emission solenoids come in only 2 varieties, so just find one that looks the same (note the filter port location). They're the same on all FCs.

Have you always had hot-start flooding issues? The stock ECU has a pretty rich start map, and compression reduction over the years will lead to difficulties. Another less common source of issue can be leaky injectors dripping after the engine is shut down.

 

The first time I had the hot flood happen I started the car, pulled it out of the garage and turned it off. Then I learned to let it warm up. This was 2 summers ago.

Took it out today, drove all over the place, made a few stops. no problems. Then one one stop it was hard to start, strong smell of fuel, etc. Got it to start by flooring and holding while cranking. Next stop, same deal but it started a little easier. I drove at least 15 miles between each stop and the car was off for maybe 30 minutes each time.

 

Also, I've seen where the injectors should be bagged when removed to prevent them from drying out. I didn't do this. The upper injectors sat for about 3 weeks, unbagged.
